Not nearly big enough to get hit an average of even once per trip, let
alone 40, if Keith means the designs I think he means.

Especially if the trips are plotted to avoid tracked debris; I was
literally just yesterday looking at the US government's latest service to
check such trajectories and confirm they'll be free of known debris, and
they have access to good enough radar to track almost anything large enough
to matter.  (Acknowledging that "large enough" is very small, given orbital
velocities.  They still track it.)
